Kalanchoe plant named ‘Aniak’

ABSTRACT

A new and distinct cultivar of  Kalanchoe  plant named ‘Aniak’, characterized by its upright, compact and uniform growth habit; freely branching plant habit; glossy leaves; uniform, freely and early flowering habit; large red purple-colored flowers; and excellent postproduction longevity.

Botanical designation: Kalanchoe blossfeldiana.

Cultivar denomination: ‘Aniak’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Kalanchoe, botanically known as Kalanchoe blossfeldiana, and hereinafter referred to by the name ‘Aniak’.

The new Kalanchoe is a product of a planned breeding program conducted by the Inventor in De Lier, The Netherlands. The objective of the breeding program is to create new freely-branching and freely-flowering Kalanchoe cultivars with attractive foliage and flower coloration.

The new Kalanchoe is a naturally-occurring whole plant mutation of the Kalanchoe blossfeldiana cultivar Lokon, not patented. The cultivar Aniak was discovered and selected by the Inventor as a flowering plant from within a population of plants of the cultivar Lokon in a controlled environment in De Lier, The Netherlands in November, 2002.

Asexual reproduction of the new Kalanchoe by vegetative terminal cuttings in a controlled environment in De Lier, The Netherlands since the spring of 2003, has shown that the unique features of this new Kalanchoe are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Aniak has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, daylength and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Aniak’. These characteristics in combination distinguish ‘Aniak’ as a new and distinct cultivar of Kalanchoe:

-   -   1. Upright, compact and uniform growth habit.     -   2. Freely branching plant habit.     -   3. Glossy leaves.     -   4. Uniform, freely and early flowering habit.     -   5. Large red purple-colored flowers.     -   6. Excellent postproduction longevity.

Plants of the new Kalanchoe can be compared to plants of the parent, the cultivar Lokon. Plants of the new Kalanchoe differ from plants of the cultivar Lokon in the following characteristics:

-   -   1. Plants of the new Kalanchoe are not as compact as plants of         the cultivar Lokon.     -   2. Plants of the new Kalanchoe are more freely branching than         plants of the cultivar Lokon.     -   3. Leaves of plants of the new Kalanchoe are longer and have         longer petioles than leaves of plants of the cultivar Lokon.

Plants of the new Kalanchoe can be compared to plants of the Kalanchoe blossfeldiana cultivar Petero, disclosed in U.S. Plant Pat. No. 12,155. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Kalanchoe differed from plants of the cultivar Petero in the following characteristics:

-   -   1. Plants of the new Kalanchoe were slightly smaller than plants         of the cultivar Petero.     -   2. Leaves of plants of the new Kalanchoe were smaller and had         shorter petioles than leaves and petioles of plants of the         cultivar Petero.     -   3. Plants of the new Kalanchoe had larger flowers than plants of         the cultivar Petero.     -   4. Plants of the new Kalanchoe and the cultivar Petero differed         in flower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Kalanchoe, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Kalanchoe. The photograph comprises a side perspective view of a typical flowering plant of ‘Aniak’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown in De Lier, The Netherlands in a glass-covered greenhouse during the autumn and under conditions which closely approximate commercial production. During the production of the plants, day temperatures ranged from 19° C. to 26° C., night temperatures ranged from 20° C. to 21° C. and light levels ranged from 10,000 lux to 50,000 lux. Unrooted cuttings were directly stuck in 10-cm containers and received long day/short night conditions (more than 14 hours of light) for about four weeks; plants then received photoinductive short day/long night conditions (minimum 14 hours darkness) until flowering. Plants were about 14 weeks old when the photographs and the description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
